This is a sample page. It's different from a post because it stays in place and will show up in your site's navigation (in most themes). Most people start with an About page, which introduces them to potential site visitors. It could be something like this:

Hello! I'm a messenger by day, aspiring actor by night, and this is my blog. I live in Madrid, I have a big dog named Duque and I like pina coladas (and getting caught in a downpour)

…or something like that:

La empresa XYZ se fundó en 1971 y ha estado ofreciendo «cosas» de calidad al público desde entonces. Situada en Madrid, XYZ emplea a más de 2.000 personas y hace todo tipo de cosas sorprendentes para la comunidad de Madrid.

If you are new to WordPress you should go to your desk to delete this page and create new pages with your own content. Have fun!
